There are a couple of Yamahas we can ECU remap – R1 model years 2007-2008 and 2012-2014, plus R6 2006-2011 – but not many. Hopefully, that will change with time. However, bikes like the single-cylinder XT660X (plus the other models that use the same basic platform) respond well to a good ol’ Power Commander, as stock they’re tuned for emissions purposes more than anything else…

Now the bike below isn’t Kevin’s XT but one very like it, but he took the time to drop us a line when he got home with his thoughts. Thanks mate!

Hi Gill/Mark,

Just to say a big thanks for today, i appreciate you sorting the XT out for me. Could not resist a spin out on it when i got home! The fuelling is spot on now! And i am well pleased with it. It has transformed the bike and is now a pleasure to ride, and was worth every penny.

I will have no hesitation recommending BSD to anyone who asks me in the future.

All the best,

Kev Brown

Not Kevin's XT, but a nice shiny studio shot of a stocker – needs a Power Commander, of course...
